Be it k nown that we, lurmrr SUULACUTER and FRITIOF HnrN'rz, citizens ofthe United States, residing at Streator, in the county of La Snllc andState of Illinois, have invented certain new and useful Improvements inGlass Melting Furnaces and Regenerators; and we do hereby declare thatthe following isafnll, clear, and exact description of the same,reference being bad to the annexed drawings, making a part of thisspecification, and to the letters and figures of reference markedthereon.

higure l of the drawings is a top plan View or our invention, partly insection; Fig. 2, a longitudinal section through the melting chamber;Fig. 3, a top plan View thereof, showing the interior construction; andFig. 4,21 transverse vertical section.

The present invention has relation to that class of glassinel ti ngfurnaces and regenerators for which a patent was granted toFritioi'Heintz May 17, 1887, No. 362,961, and is designed as animprovement thereon.

The object oi" the invention is to improve the construction of thefurnace and regenerator, wherein a double furnace is provided which willrequire less fuel, melt glass much better and quicker, and is equallywell adapted to working any and all kinds of glass of any descriptionwhatever, a double tanlr being provided with two separate generators andproducers on each end or side 01' the furnace, so that one set ofproducers will melt the glass in the meltingtank and the other set :illmelt and clear the glass in the clearing and working tank.

The object of the invention whereby these advantages are attained wiilhe hereinafter described, and subsequently pointed out in the claims.

In the accompanying drawings, A represents the mclti n g-tank orcombnstioircliainber, in which is placed the material to be melted, saidtank or chamber being lined with fire brick or other similar materialusually employed as a lining for this class of furnaces. The furnace ispreferably made shallow and of any suitable length and height, so thatthe material placed therein will be equally exposed to the heat of theburning gases in order to facilitate the melting process.

At the sides of the melting-tank or combustion-chamber A are thechambers B G, which communicate therewith by lines D; or, if preferred,instead of continuous lines, a series of ports may be used, is common inthis class of furnaces.

The melting-tank or coinbustiolrchamber is separated from the chambersabove described by means of the open spaces E, which serve to keep thewalls of the tank or combustionehamber cool, in order to protect thesame from excessive heat.

The chambers B C are provided with division-walls, which divide theminto two compartmcnts, H and I, the former being the airregeneratingchambers and the latter the fines or chambers through which the gas isadmitted to mingle with the air and effect a complete combustion.

Instead of a single set of gas producers or generators, as in the patenthereinbefore referred to, two sets are employed, as shown at J K, andmay be of substantially the same construction, or any of the kindusually employed in this class of furnaces, and are connected with thefurnace by pipes L M and pipes J 0. At the juncture of these pipes arereversing-valves P, of any wellknown form and construction, whichcontrol the direction of the gas.

The clearing-rank and the working-tank are divided by a partition, it,extending crosswise of the furnace, and the partition is provided withan opening, a, at its lower edge to let the glass pass through from theclearing-tank into the working-tank. This partition, which is preferablyconstructed of stone, is dovetailed in the furnace-bottom to keep thepartition from rising up when glass is melted.

The melting-tank and the clearing-tank are divided by a partitionextending crosswise of the furnace and from the bottom of the fur naceto the arch which covers the top of the tanks. This partition is toextend crosswise through. the gas and air rcgcnerators on both sides oron both ends, and has openings 1) on bottom edge, where it rests ontank-bottom, so that the melted glass can run through from themelting-tank A into the clearingtanl; A, and thence through the openingin the partition into the workingtanlr A.

By melting glass in a furnace constructed in accordance with ourinvention the glass can be heated to a higher grade of heat in themelting-tank while in operation, while at the same time the heat can beregulated in the clearing and the working tanks to suit the glass forthe best working capacity, while the glass can be worked and gatheredwithout its getting cold from the cold air blowing in from thegathering-ring holes 0 at the end of the furnace. The holes (Z at theopposite end of the furnace are for the purpose of putting in thennmelted batch.

The partition S,hereinbefore referred to, will prevent the cold air frompassing through the furnace, either from one end or the other, or fromeither side, when the holes or openings are exposed to gather the glassor to put in the batch, and will also separate the burning gas and airfrom the working part and the melting part.

The two cold air flues which divide the sides of the tank and thegenerators have a suitable number of chimneys, T, through them, whichpass up through the top of the furnace and will draw through the heatedair which accumulates while the furnace is in operation; otherwise thisair would come out either one end or the other and make it disagreeableto the men at the furnace.

The sides of the furnace may be provided with holes and arches for thepurpose of taking out the brick-work and examining the generators whilethe furnace is in operation.

The interior construction of the chambers B C is substantially the sameas those shown and described in the patent upon which the presentinvention is designed as an improvement.

The checker-brick U and the deflecting-brick V are substantially thesame as those employed in the patent herein referred to, andarescparated by a suitable partition, 6.

The pipes or lines L M and N O, which connect with the gasproducers orgenerators K also connect with the regenerator-chambers H, therebyforming a communication between the chambers and generators. These llnesconnect with the main fines XV,which lead from the gasproduccrs, and thetwoway valves 1?, which may be of any well-known construction, directthe flow of gas either in one or the other of the fines, as occasion maydeem necessary.

Leading from the exit-ports of the regenerator-chambers H are flues B Gat each end of the furnace, said fines communicating with valve-boxes D,which are provided with suitable valves, as shown in dotted lines, forreversing the direction of the products of combustion and permittingthem to escape to the fines E, and thence therefrom to the stack F.

The deflectors V are located below, and are separated from theregenerator-brick, as hereinbefore described, and check the volume ofgas and direct it into the fines E. The fines G, which also communicatewith the stack F, project from the valves Rand are for the purposc'o'fconducting off the waste or escaping as.

b Having now fully described our invention, what we claim as new, anddesire to secure b Letters Patent, is-

1. The combination, in a glass-melting furnace provided withrcgenerators on each side, of two separate tanks, one of said tanksbeing provided with a partition, a partition-wall eX- tending throughsaid furnace entirely separating said tanks except by an opening oropenings at its bottom, said partition also dividing the regeneratorsinto two distinct portions, and separate gasprodncers connected by finesand suitable valves to each of said portions, substantially asdescribed.

2. The combination, in a glassmclting inrnace provided with regeneratorson each side, of two separate tanks, a partition-wall extend ing throughsaid furnace entirely separating said tanks except by an opening oropenings at its bottom, said partition also dividing the regeneratorsinto two distinct portions, and separate gas-producers connected byfines and suitable valves to each of said portions, substantially asdescribed.

In testimony that we claim the above we have hereunto subscribed ournames in the presence of two witnesses.
